iommupt: Fixup build warning by using BIT_ULL() for RISCVPT_NC/IO

[PATCH] iommupt: Fixup build warning by using BIT_ULL() for RISCVPT_NC/IO

Posted by fangyu.yu@linux.alibaba.com 1 month ago

From: Fangyu Yu <fangyu.yu@linux.alibaba.com>

Fix build warning on 32-bit configurations by using BIT_ULL() for
RISCVPT_NC and RISCVPT_IO.

Fixes: 6c21eb174c6c ("iommupt: Encode IOMMU_MMIO/IOMMU_CACHE via RISC-V Svpbmt bits")
Reported-by: kernel test robot <lkp@intel.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202605121350.wZxB51k0-lkp@intel.com/
